QUESTION 22You need to identify the minimum number of required public IP addresses for each Skype for Business Server 2015 component.How many public IP addresses should you reserve for each component? (To answer, select the appropriate number servers in the answer area.)

Answer: CHKPExplanation:Contoso must minimize hardware and software purchasing costs, while guaranteeing performance levels for all Lync Server 2013 workloads. If a single component fails, all Lync services must remain available without the need for manual intervention. Performance degradation is acceptable during a component failure state.For the number of users, 3 FE servers are required. In the event of a failure, one server could not handle 15,000 users.SQL mirroring is the recommended database HA solution in Lync 2013. To avoid manual intervention, you need a third server to act as a witness server.You could use a failover cluster using two servers but this tends to be more expensive in terms of hardware cost.
